I am doing my engineering with major in electronics. I like coding but I like the Hardware part more.I have taken two courses: CEH & eCPPT.I wanted to know is there any course on something like hardware security?My special interest is in server and nano programming.Please help!

Maybe the others here will have a better understanding what you mean by Hardware Security, but could you explain it to me?

Right now, all I can think is the physical hardware security of the systems. Things like limiting access; filling the device with epoxy to prevent parts being added, removed or modified; tamper evident labels on teh devices; etc.

I don't know of any official training, but you should look for local DefCon groups and other hackerspaces and/or attend conferences and do some networking at the hardware hacking villages. There are definitely others out there that have similar interests.

The CISSP has a domain on Physical Security, but that is the only cert that I know of that does.

Beyond the defcon groups try to find a local lock sport group. those usually have people all about physical security in them. Somewhere else to look is Maker Spaces. they'll get physical with the hardware.
